Thanks Greg for your reply, I appreciate it very much and will take all your suggestions to heart.
I have two other extremely knowledeable individuals working with me on this problem, Jan Lewandoski, and Robert Porthouse. Each individual has alittle different approach, but all in all they are very close in their suggested remedy and repair proceedure.
Between the two of them and suggestions from people like yourself I feel confident that a local construction company can procced safely, using their and your guidelines.
Once again on behalf of the St. Peter's congregation in Williamsburg Ontario I say thank you for your time and remarks.
Your comments about working carefully is well taken, and will be heeded.
